Modern Murphy Bed Bookcase.
It's a simple but very effective set up: the shelves can hold books or other items that are rented completely hidden and only the small footprint upright bed remains useless. A twin is the right size to accommodate the occasional overnight visitor. This means that a thoughtful designer can hide a side tilt Murphy bed using a variety of non-traditional methods.
